RADIATOR.

Specification of Letters Patent.

Patented July 15, 1919.

Application filedlTune 26, 1917. Serial No. 177,095.

To all iii/mm it may concern Be it known that I, J osnrn J. RUSSELL, a citizen of the United States, residin at T0- ledo, in the county of Lucas and btate of Ohio, have invented new and useful Im- -proyements in Radiators, of which the ,fol-

lowlng is a specification.

This invention relates to radiators such as are now commonly used in motor vehicles for cooling the water of circulation which pass through the jacket of the engine.

The object of the present invention is to produce a radiator in which the core as a whole is made up of several sections each of which is so constructed and mounted that it may be removed from the casing or housing of the radiator without removing or interfering with any of theother sections, enabling a leak or repair of any kind to be made at any point in the removed section.

A further object of the invention is to construct each of the sections of the core in such manner that the water tubes are capable of expanding in case of the water freezing, without serious injury thereto.

lVith the above and other objects in view,

: the invention consists in the novel construction. combination and arrangement of parts,

herein described, illustrated'and claimed.

In the accompanying draw1ngs: Figure l a vertical longltudinal section through a radiator illustrating the improved construction.

Fig. 2 is an enlarged vertical transverse section on the line 2-2 of Fig. 1.

F ig. 3 is a fragmentary section on the line 3-3 of Fig. 2.

Fig. 4 is a detail view illustrating the end connections between the horizontal runs of the water tubes.

Referring to the drawings 1 desimiates a radiator casing which may be of any desired contour. the same being provided with the usual filling neck 2 and cap 3.

In carrying out the present invention in the preferred embodiment thereof, the easing 1 has mounted therein a comparatively small top water compartment 4 and also a comparatively small bottom water compartment 5. the top compartment (Oll'lpl'lfilflg an iii-cuate bottom wall 6 and the bottom oompai-tincut comprising a top arcuate wall 7.

it designates the water inlet opening and 9 the water outlet opening.

'llie radiator is shown as comprising three core sections a (i a as shown in Fig. 1 but it will be apparent that the number of sections may be increased or diminished at will and in accordance with the desired water capacity of the radiator. Each of the sections comprises a plurality'of horizontal rims b which are connected at numerous points by vertically extending strips 0 of metal which form connecting Webs or braces between the horizontal runs 7) of each section a of the radiator core.

eferring now to Figs. 2 and 3, each of the horizontal runs 6 is composed of atop plate 10 and a bottom portions 12 and the rear portions 13 of said plates lie in contact with each other and are soldered as indicated at 14 to form water tight joints to prevent leakage. The intermediate portions of the plates 10 and 11 are of stepped formation as clearly shown in Fig. 2 and are arranged in spaced relation to each other to leave a central horizontal waterway or passage 15, a downwardly ta pering or contracting waterway 16 and an upwardly tapering or contracting waterway 17. All of the runs 6 are of corresponding formation as shown in Fig. 2 thereby leaving zigzag or-sinuous air passages (Z between the superimposed horizontal runs b. The portions 12 and 13 of the top and bottom plates '10 and 11 are only connected at their extreme outer edges thus providing for expansion in case the water should freeze in the water tubes. This prevents serious injury to the water tubes. ends, the runs 6 are connected by end chain bers or vertical runs e each comprising an inner wall 18 and an outer wall 19. The connections c are arranged in the manner illustrated in Fig. 1 so. as to provide for the continuous movement of the circulating water from top to bottom of each core section.

Each of the core sections a is provided at its upper end with an inlet cmineetion 20 controlled by a stop cock 21 and connected by a liquid tight union 22 to the wall 6 of the top water compartment; 4. In like mannor the lower end of each core section is connected, by a conduit controlled by a stop rock 24 to the wall 7 of the bottomcompartment 5 by means of a liquid tight union 2:"). The. construction just referred to enables the water to be cut off both at the top and bottom end or" each core section and also cii ables each core section to be disconnecled at: the top and bottom thereof from the lop and bottom water compai'l'inents in order that plate 11. The front At their opposite any desired section may be removed from the casing or housing of the radiator.

The construction hereinabove described greatly facilitates the assemblage of the es sential parts of a radiator and enables re pairs to be readily made by removing any section which needs repair. After a core section lsremoved from the casing 1, the

vertical strips 0 may be cut or severed bev tween any pair of runs 6 thus enabling the said runs to be sprung apart' sufliciently to facilitate the'resoldering or repair of the water tubes.

I claim 1. In a radiator, a core comprising a verand bottom plates being of stepped for1na tion and arranged in spaced relation to each other to provide a central substantially horizontal waterway and inclined Waterways at a the front and rear of said horizontal water 2 In a radiator, a core comprising a vertical series of terminally connected substantially horizontal runs, each run embodying a top plate and a bottom plate having their v front and rear portions arranged'in contact with each other and united by a water tight joint, the intermediate portions of said top andbottom plates being of stepped formation and arranged in spaced relation to each other to provide a central substantially horizontal Waterway and inclined Waterways at the front and rear of said horizontal'waterway, said inclined waterways being of tapering or contracting formation toward the front and rear connected portions of said top and bottom plates.

3. In a radiator, a core comprising a vertical series of terminally connected substantially horizontal runs, each run embodying a top plate and a bottom plate having their front and rear portions arranged in contact with each other and united by a water tight joint and their central portions arranged in horizontal parallelism and spaced apart to provide a central rectangular portion and upwardly and downwardly extending front and rear downwardly tapered portions, extending from and communicating with the central rectangular portion to provide extensible waterways and air passages having restricted central portions formed by the central rectangular port-ion of the Waterways.

In testimony whereof I aiiix my signature.
